I agree. My home screen personal view says "Satisfaction survey (30 on 150)". Most of these surveys are expired. I can't remove them. Once the survey has expired they shouldn't be listed any more.

I use the pending feature for this and create a task>information with a description of why the ticket is pending.

Custom pending statuses would be nice but not sure if could be easily implemtented.
